Interplay of orbital and spin ordering in the iron pnictides
Andriy H. Nevidomskyy
A number of recent experiments exhibit electronic anisotropy in the iron pnictides, and there is a growing body of experimental evidence that its origin is related to orbital order…
Kondo resonance narrowing in d- and f-electron systems
Andriy H. Nevidomskyy, P. Coleman
By developing a simple scaling theory for the effect of Hund's interactions on the Kondo effect, we show how an exponential narrowing of the Kondo resonance develops in magnetic io…
Layered Kondo lattice model for quantum critical beta-YbAlB4
Andriy H. Nevidomskyy, P. Coleman
We analyze the magnetic and electronic properties of the quantum critical heavy fermion superconductor beta-YbAlB4, calculating the Fermi surface and the angular dependence of the…
Magnetism and d-wave superconductivity on the half-filled square lattice with frustration
Andriy H. Nevidomskyy, Christian Scheiber, David Senechal +1
The role of frustration and interaction strength on the half-filled Hubbard model is studied on the square lattice with nearest and next-nearest neighbour hoppings t and t' using t…
Convexity of the self-energy functional in the variational cluster approximation
Andriy H. Nevidomskyy, David Sénéchal, A. -M. S. Tremblay
In the variational cluster approximation (VCA) (or variational cluster perturbation theory), widely used to study the Hubbard model, a fundamental problem that renders variational…
Coexistence of ferromagnetism and superconductivity near quantum phase transition: The Heisenberg- to Ising-type crossover
Andriy H. Nevidomskyy
A microscopic mean-field theory of the phase coexistence between ferromagnetism and superconductivity in the weakly ferromagnetic itinerant electron system is constructed, while in…
